that's the celebration in the heart of washington, d. c. and urban areas and places where there was a lot of diversity and put president obama over the top in this election. when you look at the vote count it will show that president lost with white men but won big with latinos and huge with african americans and was able to use the gender gap and won a majority of the women voters. >> the youth vote also critical and so many made their opinions known or facebook and twitter. let's go to kristin. >> reporter: as you can imagine today, twitter, facebook was just blowing up. everybody voicing their opinions, sharing pictures and whatnot. i'm joined by web producer simon lamb. this is called the trends map. it shows you what people are tweeting about. right before it was announced obama has been re-elected, this was empty. now it is completely full with people tweeting. today they got up to about 20 million votes, one of the largest in political history as you can imagine. i can't even imagine what it is like once that was originally announced
